History The Mississippi River originates as a tiny outlet stream from Lake Itasca in northern Minnesota. During a meandering 2,350 mile journey south to the Gulf of Mexico, the Mississippi River is joined by hundreds of tributaries, including the Ohio and Missouri Rivers. Water from parts or all of 31 states drains into the Mississippi River, and creates a drainage basin over 1,245,000 square miles in size. Before reaching the Gulf, the Mississippi meets up with its distributary, the Atchafalaya River.

- Map the Mississippi Watershed! Teacher Notes: 2. The Mississippi Watershed is all the land area that drains into the Mississippi River. On the map the watershed (or “basin”) boundary is indicated by the dashed line that encircles all Mississippi River tributaries. 4. By definition the Mississippi River starts at Lake Itasca in northern Minnesota. However, it can also be said that the Mississippi River starts wherever rain or snow falls in the Mississippi Watershed, because water that flows from land anywhere in the watershed will eventually flow into the Mississippi River.
